German centromat workholding fixtures centromat model centromat price

centromat workholding fixtures use hydraulic components to replace mechanical parts, achieving automatic positioning, support, and clamping of the workpiece through hydraulic control. They offer advantages such as high clamping force, reliable clamping, stable operation, and ease of use. They are currently widely used in scenarios such as CNC machine tools, machining centers, and automated production lines. By assembling the selected hydraulic components with the designed mechanical parts, the required fixture can be obtained. Hydraulic fixtures ensure accurate positioning and secure clamping of the workpiece at the specified location, and can reduce vibration and deformation during machining through floating supports. They can also use automatic control to press down and lift the pressure plate to clear the clamping position during machining. Hydraulic fixtures can withstand large cutting forces during rough machining, ensure accurate positioning during precision machining, and perform support, clamping, and quick release tasks that manual fixtures cannot complete.

centromat workholding fixture types

1) Standard rectangular electromagnetic chuck Application: Rectangular table surface grinders. 2) High-power electromagnetic chuck Application: Milling machines, planers, machining centers. 3) Fine-pole electromagnetic chuck Application: Rectangular table surface grinders, milling machines. 4) Multi-function high-power electromagnetic chuck Application: Rectangular table surface grinders. 5) Rotary electromagnetic chuck Application: Various surface grinders. 6) Electromagnetic chuck for tool grinding Application: Tool grinding machines. 7) Circular electromagnetic chuck (concentric circle type) Application: Circular table surface grinders. 8) Circular electromagnetic chuck (radial pole type) Application: Circular table surface grinders. 9) Circular electromagnetic chuck (plum blossom pole type) Application: Circular table surface grinders. An electromagnetic chuck is an electromagnetic fixture that secures the workpiece being machined through the suction force generated by the chuck body after the electromagnetic coil is energized. The electromagnetic chuck consists of several parts, including the iron core, coil, faceplate, and bracket. The electromagnet, composed of the coil and iron core, is the main part of the electromagnetic chuck.

centromat workholding fixture operation

1) Assemble the two engine bushings onto the 1 strut according to the "Strut Welding Assembly" drawing, and place them on the fixture body, position the 1 strut using stop pins and stop plates, clamp the 1 strut with a spiral clamp; simultaneously position the two 4 engine bushings with pins, and clamp them with quick-release spiral clamping devices; 2) After tack welding, release the quick-release spiral clamping devices, pull out the pins, remove for welding; 3) Place the welded assembly back on the fixture body, position the welded assembly using stop pins and stop plates, clamp the welded assembly with a spiral clamp; then place the assembly of the M6 nut and horn bracket onto the welded assembly, position it using the conical pin on the spiral clamping mechanism and the groove on the pressure plate of the spiral clamping mechanism, and clamp it with the spiral clamping mechanism; 4) Perform three-side welding on the assembly of the M6 nut and horn bracket and the strut, then release all spiral clamps, the pressure plate of the spiral clamping mechanism clamping the M6 nut and horn bracket assembly is lifted by the spring, the positioning conical pin on it disengages from the welded assembly, then push out the pressure plate to disengage one end from the spiral clamping mechanism stud, rotate the pressure plate to the side of the welded assembly, then remove the welded assembly.

centromat workholding fixture applications

1) Can stably ensure the machining accuracy of the workpiece: When clamping the workpiece with a fixture, the positional accuracy of the workpiece relative to the tool and machine tool is ensured by the fixture, unaffected by the worker's skill level, making the machining accuracy of a batch of workpieces consistent. 2) Can reduce auxiliary time and improve labor productivity: Using fixtures to clamp workpieces is convenient and fast. Workpieces do not need scribing and alignment, significantly reducing auxiliary time. Clamping workpieces in fixtures improves their rigidity, allowing for increased cutting amounts. Fixtures for clamping multiple workpieces or multi-station workpieces can be used, and high-efficiency clamping mechanisms can be adopted to further improve labor productivity. 3) Can expand the usage range of machine tools and achieve multi-functionality: According to the forming motion of the machining machine tool, attaching different types of fixtures can expand the original process range of the machine tool. For example, installing a boring template on the slide board of a lathe or the worktable of a radial drilling machine allows for boring processing of box parts. 4) Ensure machining accuracy: Using fixture installation can accurately determine the mutual position between the workpiece and the machine tool/tool. The positional accuracy of the workpiece is ensured by the fixture, unaffected by the worker's skill level, resulting in high and stable machining accuracy. 5) Improve productivity and reduce costs: Clamping workpieces with fixtures allows for rapid positioning and clamping without alignment, significantly reducing auxiliary time. Clamping workpieces with fixtures improves their rigidity, thus allowing for increased cutting amounts. Multi-piece and multi-station fixtures can be used to clamp workpieces, and high-efficiency clamping mechanisms can be adopted. These factors are all conducive to improving labor productivity. In addition, after adopting fixtures, product quality is stable, the scrap rate decreases, workers with lower technical grades can be assigned, significantly reducing production costs. 6) Expand the process range of machine tools: Using special fixtures can change the original purpose of the machine tool and expand its usage range, achieving multi-functionality. For example, after installing boring template fixtures on lathes or radial drilling machines, boring processing can be performed on box hole systems. Special fixtures can also convert lathes into broaching machines, fully leveraging the role of general-purpose machine tools. 7) Reduce workers' labor intensity: Clamping workpieces with fixtures is convenient and fast. When using pneumatic, hydraulic, and other clamping devices, workers' labor intensity can be reduced.
